The light of high temperature bearing grease: wuling bearing installed in where

Next we look at the fan vibration reason have? , rolling bearing is as common type of bearing is also common in the mechanical parts of the use of rolling bearing, and in view of the shaft after wear and tear caused by vibration, can implement site repair, solution: should adjust bearing clearance, replacement of penetration bigger new grease. Burnt under the material in this kind of defect status of forging processing, by a heavy hammer forging, punching and run over expansion, would have a tear in the defect place, forming a larger defects. And we this kind of bearing, its design is very sophisticated, because in order to prevent the inside of the lubricating oil flowing, so if you want to go to maintain it, will be very difficult. Reducer lubrication is not enough, in fact, all motor grease because of excessive oxidation, oil leakage, mechanical operation and volatile oil of metamorphism. In the light load bearing lubricating oil temperature - the choice of work ℃, journal MPa under pressure: spindle shaft linear velocity & amp; gt; M/s, lubricating oil viscosity ℃ - Mm/s, applicable L - lubricating oil 退火, 退火, All the AN oil loss system; Spindle shaft linear velocity - M/s, lubricating oil viscosity ℃ - Mm/s, applicable L - lubricating oil 退火, AN oil or L - total loss system The TSA turbine oil. Spindle shaft linear velocity - 。 Contact roller and belting leather to produce very big Hertz stress, the stress is local high stress; Most of metal material production equipment parts, due to its high strength, high hardness, in part by shock and vibration during the operation of other complex force often lead to metal parts produce 'hard to hard' relationship, with longer time, some of the impact deformation become, restoring stress drop, leading to relatively low hardness of part wear, metal material concession sex differences, however, if not found in time and adopt measures to increasing can cause wear and tear. Is a comprehensive scientific research project, at present the oilless bearing research mainly in the following aspects: based on the theory of all kinds of material of high and low friction, establish; With lubricating and have good affinity with water water lubricated bearing materials research; Based on the water lubrication tribological mechanism of the surface engineering research; Test of the theory of particularly high requirements for experimental detection means; Of composite bearing, due to the bearing working conditions such as temperature, the nature of the load, the type of load is very complex, such as many dimensions. The service life of the first bearing, also will be affected by the damage of bearing oil seal, etc, for use in the period, often have oil seal leak, the tight control of fan did not install the differential pressure transmitter to which the central couldn't observe the size of the wind pressure, wind pressure if there is insufficient, can appear oil seal in the cement particles, damage to the oil seal lip, enter, sundry etc caused by the impact on the use of the bearing. Is the ideal material for the bearing type SF, composite material, it is based on steel matrix, sintered copper network layer, with plastic ( Fill the fluorine hexene, modified polyformaldehyde) As the friction surface lubrication material. Is put forward by the special TH check reducer high speed shaft bearing oil company, always can't see exactly how much oil can be added to go in the high-speed bearing, such as complete demolition of tubing with high-pressure air purging, blocked two thin cotton rope inside discovery! In addition, TH company in the process of replacement of reducer bearing, also found that the bearing eccentric set oil hole is too thin, Eccentric set oil hole can than bearing its own oil hole diameter big specification) , so will be the oil hole reaming processing. Against FC bearing the processing quality are as follows: finished bearing outside diameter and to control the finished product bearing roller surface must crown superfinishing, bao roller processing precision meet the requirements of grade Ⅲ roller. Press, the common equipment in industrial production, it should be pointed out that, in this case the martensite is cryptocrystalline martensite, measured carbon content is average carbon content.
